Batteries are rated in milliamp hours (abbreviated mAh) or watt-hours (abbreviated Wh). A fully charged battery can provide about an hour of illumination to an LED strip.
To charge the battery, insert it into the charger with the terminals oriented correctly. The CHARGE LED will illuminate the RED while charging and GREEN when fully charged.
Connect the Battery How to Connect Led to the Battery Charger:
Before connecting the battery charger to the battery it is important to make sure that all connections are tight.
This will help prevent a potentially dangerous short between the battery and wires. It is also important to use the correct wire size.
A larger wire will be needed for longer runs, whereas a smaller wire will be required for shorter runs.
Once the charger is connected to the battery it should be left alone until the charger indicates that the battery has been charged. This is usually indicated by a GREEN CHARGE LED that is not blinking.
Once the charger has finished charging the battery it is time to disconnect it. This should be done in reverse of the order that it was connected, starting with the black cable (negative terminal) and then the red wire (positive terminal).
Be careful not to touch the positive or negative battery terminals, as this could cause a life-threatening shock.
Connect the Power Cable:
Make sure that the charger’s power cable is connected to a power source. Verify that the plug is properly connected to a grounded three-prong outlet and that it has the proper wire size for the amperage of the battery charger.
Connect the positive lead from the charger to the positive terminal on the battery, which is usually red with a plus sign.
Connect the negative lead from the charger to the negative terminal on the battery. Which is typically black with a minus sign.
Verify that all connections are secure and that the charger is set to the off position. Allow the battery to charge until it is fully charged, which can be verified by checking the charger’s display or using a voltmeter. Unplug the charger when the battery is fully charged.
